Well, you should wait a week after getting a perm to dye it, but what do you mean by using two boxes of hair dye? If you have long hair and you'd need two boxes to cover your hair, then it would be no problem. It's when you dye your hair and then a couple day later dye it again and so on, that does the damage.
i use 2 boxes of hair dye but that is because how long my hair is and it really depends how long ur hair is as well like if it is really long then u probely need 2 boxes but if ur hair is short then probely 1 box. and idk about the perm queastion u probely shouldnt just in case.
As for the boxes, you can mix shades, use two if you have long hair or whatever isn't bad, but I'd wouldn't dye my hair right after getting a perm, it seems like a bad idea. But check the box.
Well, as for the two boxes thing thats fine =) I do that all the time cuz I have really thick hair. (p.s. my mom's a stylist so it's ok X)
yes hair dye is a chemical and if u use to much of it u can fry ur hair and u would not want to do that
my cousin did that two weeks before her wedding. DONT DO IT.
